As you may have seen in recent news, Los Angeles is currently battling immense destruction from wildfires. Described by some as apocalyptic, these wildfires mark a devastating start to the new year. While wildfires are a natural disaster that has occurred for centuries, the increasing frequency, intensity, and unpredictability of these events demand a closer look at their causes and connection to climate change.
How Wildfires Get Started
Wildfires are typically ignited by natural causes such as lightning strikes or human activities like unattended campfires, discarded cigarettes, and utility line failures. The wildfire season traditionally spans the hottest and driest months of the year, when vegetation becomes a tinderbox waiting for a spark.
The perfect conditions for wildfires include:
Dry vegetation: Prolonged periods of little to no rain turn plants into highly flammable fuel.
High temperatures: Heat dries out vegetation even further, making it more combustible.
Strong winds: These can spread flames rapidly across vast areas, making containment efforts challenging.
However, it is crucial to note that wildfires are not new. They are a natural ecological process in many areas, contributing to forest regeneration by clearing out dead materials and allowing for new growth. But the scale of destruction we’ve seen in recent years—from LA to Canada—is unprecedented. For example, the 2023 wildfires in Canada were so severe that their smoke traveled hundreds of miles, deteriorating air quality in major cities like New York and Detroit.
Why Are Wildfires Becoming More Frequent and Devastating?
While wildfires have always occurred, the reason we’re seeing them more often and out of season lies in the connection to climate change. Here’s why:
Rising Temperatures
Global warming is increasing temperatures worldwide. In regions like California, hotter weather dries out vegetation faster, creating prime conditions for fires to ignite and spread.
Prolonged Droughts
Climate change is intensifying droughts, which reduces the moisture content of plants and soil. This exacerbates fire risks even outside traditional wildfire seasons.
Extreme Weather Patterns
Strong winds, a hallmark of many wildfire-prone areas, are becoming more intense and erratic due to climate disruptions. This accelerates the spread of fires and makes them harder to control.
Human Impact
Urban expansion into fire-prone areas increases ignition risks. Combined with climate change, human activity has amplified the scale and devastation of wildfires.
The Role of Climate Change
Climate change is not just a backdrop to these events; it is a key driver. Scientific research consistently links global temperature rises to the increasing severity of wildfires. In California alone, the area burned annually by wildfires has increased fivefold since the 1970s, and experts predict this trend will continue if greenhouse gas emissions are not curbed.
The Canadian wildfires in 2023 and their impact on air quality in far-off cities are a stark reminder that wildfires are not isolated events. They’re part of a larger, interconnected crisis that affects ecosystems, economies, and human health globally.
How You Can Help Mitigate the Effects of Climate Change
While wildfires may seem like an uncontrollable force of nature, there are steps we can take to address their root causes. Individual actions, when combined with systemic change, can make a significant difference.
